-120 degress and 1,6v GPU = 1600/1850 Mhz. Need more time for better clocks, i think it is possible.

But nice benching. Im sure you'll hit 1700 soon ;)

Yes, maybe it is depends from monitor or ports? Did you try hdmi or display ports?

slamms: what did you do to insulate on the back with the add-on card? It seems that could take some special consideration with all the frost that normally forms back there... Seems more complicated with that add-on card right where the frost mounds up typically.

What temp are you using...
Here same happens at 1.65V...so...I need to set a profile and use after working
This is the only way to fix this issue here
